Brand: Optimum Balance Products (OBP)
When you connect two brake master cylinders together using a threaded bias bar, you can adjust front-to-rear braking force to deal with different track conditions. Add a remote adjuster cable like this one and you can make quick adjustments during a race.
This cable includes a 7/16-20 threaded coupler to work with any 7/16-20 threaded bias bar, including the obp Brake Balance Bar Assembly (Part No. OBP-CB010, sold separately). Includes a compact 1.15" OD knurled billet aluminum knob assembly with 4 detents. The 1200mm (4 foot) high-strength cable is long enough for installation in just about any car, and you can easily shorten it if needed. Knob color may vary (sorry, no color choice).
Note that the knob is unmarked, so you can connect it to the left side or the right side of your bias bar to suit your installation. After installation, simply mark either the knob or the panel behind it with arrows to indicate which direction to turn the knob to increase Front braking and which direction to increase Rear braking.
